While I would agree that men as a whole choose younger women, it's also true that the younger women send stronger sexual signals; e.g., "I'm young, healthy and prepared to have your children". Perhaps nature intended younger women to be sexier and more desirable because with the help of Grandma, they can raise their children to maturity. The fact that women have a longer lifespan than men is an indication that grandmas are more important for survival of the species than are grandpas.

Because I think God has a sense of humor and I may deserve it, my wife oughta start menopause about the same time daughter starts puberty. I've told them that which ever one survives can come get me, I'll be hiding out.
